EXTENSION-TABLE.

Specification of Letters Patent.

Patented N 0V. 28, 1916.

Application-filed November 4, 1915. Serial No. 59,593.

neapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful ImprovementsinExtension- Tahles, of which the following is a specification. 7

My invention relates to extension tables and has for its objectto provide leaves for such tables having means for co mectingthe leaves in the table with their uppersurfaces in the planes of the polished end portions. as is usual, and also means for connecting the leaves in the table with the surfaces of the leaves projected above that of the table a determined distance so that protectivepads may be applied-to the polishedend portions and the surfaces of said pads will .then coincide with the surfaces of the leaves, I This makes it practicable to employ protective pads for the polished end sections of the table and to use such pads not only when the table is closed, but also when it is extended, without incurring the additional expense of securing pads to correspond to all of the leaves of the table. In accomplishing these objects I provide the end sections and adjacent leaves with dowel pins in two sets of holes in the leaves, thus permitting of in sertion at two heights. I further provide blocks under all of the leaves for raising said leaves above the level of the table, which blocks may be withdrawn or swung aside to allow the leaves to assemble in the ordinary manner.

The full objects and advantages'of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims.

In the drawings, illustrating the application of my invention in one form,Figure 1 is a bottom view of an extensionltable with my improvements employing one leaf, showing the arrangementof the dowels, holes and blocks when said leaf is elevated above ,the

rest of the table. Fig. 2 is a view similar to Fig. 1 where two leaves are employed. Fig. 3 .is a view similar to Fig. 1 where three leaves areemployed. Figs. 4, 5 and 6 are cross sectional views taken along the dowels of the table shown in Figs. 1, 2 and 3, respectively. Fig. 7 is a view similar to Fig. 6 showing the leaves assembled in the usual manner, presenting a flush top. Fig. 8 is a side .view of a portion of one of the edgesrof a leafshowing the arrangement ofthe holes for receiving the dowels. Fig. 9 is a view of a portion of a leaf showing a'modified form of elevatingblock. Fig. 10 is a view similar to Fig. 9 of a device for procuring twoheights of elevation. .7

Forthe. purpose of my invention anordinary extension table is used in which the leaves are slightly modified. InFigs. '1, 2 and 3 is shown a circular-top table 10 comprising the halves '11 and12 adapted to extend andclose up on runners 13 and 1 1. The top {portions 11 and 12 are provided as usual with dowel pins 15 and .16 which engage corresponding holes 17 and 1-8 in" the respective top portions to close the table when no leaves are used. These dowels may be arrangedas shown, part .on portion 11 and part on portion 12, orthey maybe entirely placed upon one of these portions.

Table pads are made in two halves 26 and 27 to fit a table when the same is-closed, and

these halves are usually hinged together but may be procured separate to be used with my invention.

In applying my invention three forms of leaves are used, one .form being applied when one leaf'is used, a second form being added when two leaves are used,-and a third form being added when three or more leaves are used. This will become evident from the drawings and the following description.

In Fig. 1 is showna table partly extended with a leaf 19 in place and ready to be closed up. Leaf 19, as iscustomary, is provided with holes 20 and 21 which are arranged to engage the dowel pins 15 and 1 6 when the table is used in the ordinary manner. In addition to the holes 20 and '21 are provided a second set of holes 22 and 23, as seen in Fig. 8, immediately below said lastnamed holesand drilled in blocks 2 1 and 25 glued to the underside of said leaf. With this arrangement dowel pins 15 and 16 can providing a flush surface to the whole table. Fig. 4 shows the pins 15 and 16 inserted in the lower holes 22 and 23 with pads 26 and 27 in place;

To remove most of the weight off from the dowel pins each leaf is provided with a pair of blocks 28 and 29 screwed to the respective leaves at 30 and 31 in such a manner that said blocks may be swung under the runners.13 and 1 1, or to the side as shown in dotted lines in Fig. 1, to correspond to the position of the leaves relative to said runners.

In using two leaves the leaf 19 is still maintained and an additional leaf 32 is employed. This leaf is quite similar to leaf 19 and is provided with two sets of holes 33 and 3 1 in one edge, and with dowel pins 35 in the other edge. The dowel pins 16 in the table portion 11 may engage either holes 33 or holes 3 1, depending upon whether it is desired to have the top flush or to have the leaves elevated. Dowels 35 in leaf 32 always engage the holes 21 in leaf 19, and dowels 15 in table portion 12 may, similarly to dowels 16, engage either of the holes 20 or 22 to secure the flush or elevated relation of the leaves and the top. Leaf 32 is also provided with blocks 29 which permit of the leaf being in an elevated or normal position similar to leaf 19. The relation of the parts in the elevated position is shown in Figs. 2 and 5.

When three or more leaves are used, as shown in Figs. 3 and 6, the additional leaves are all of the ordinary form, having at one side one set of holes 37 in which dowel pins 35 of the leaf 32 may be inserted, and at the other side pins 38 insertible in the holes 21 of leaf 19. Leaves 36 are, however, pro vided with blocks 29, which serve the same purpose as on the other leaves. Several of leaves 36 may be joined together and still be inserted between leaves 19 and 32. As the elevation of the center depends only upon the outer leaves, it of course becomes evident that only the outer leaves 19 and 32 need be provided with the double row of holes. The arrangement of the parts in the use of the table in the ordinary way, without the pads 26 and 27, is shown in Fig. 7 employing three leaves.

A slightly different form "of supporting block is shown in Fig. 9. Here, a block 39 is provided with a longitudinal slot 40 and through which said block is attached to the leaves by screws 11 and 42 so as to be slidable under and from in under the runner 13, as

shown in full and dotted lines, respectively, 7

in Fig. 9. Although only a single block has been shown in the drawings as supporting each end of the leaf upon the runner, yet two or more may be used where the width of the leaf is great enough to require such a number.

.The elevation of the leaves may be made in two or more heights to accommodate different thicknesses of pads by employing two or more blocks 4:4: and 15 of different heights, as shown in Fig. 10, either of which may be swung under the runner 16. This will, however, necessitate three rows of holes instead of two in the corresponding places indicated in the previous construction.

I claim:

1. In combination with the end sections of an extension table and protective pads for covering the same, a set of leaves for said table, and means for holding said leaves assembled in the table with the surfaces thereof in a plane above that of the surfaces of the end sections and in the plane of the surfaces of said protective pads.

2. An extension table comprising end sections having their surfaces in fixed planes and leaves adapted to be applied in said end sections with the surfaces thereof in the plane of the surfaces of the end sections, and means for securing said leaves in the table with the surfaces thereof above the plane of the surfaces of the end sections.

3. A table top comprising end sections and leaves for extending the table, and means for assembling said leaves in the table so that the surfaces thereof shall be exposed and in a plane above that of the surfaces of the end sections when the table is in the extended position.

4. A table top comprising end sections having a set of dowel pins in said end sections, a table leaf having thickened portions provided with two sets of apertures at different levels adjacent said dowel pins in the end sections, and movable supports on said table leaf whereby the same may be assembled in the table at either' of two levels to bring the surface of the leaf in the plane of the end sections or above the same, as
